Successful Fuel-Efficient Cookers Show the Way

By David South, Development Challenges, South-South Solutions

SOUTH-SOUTH CASE STUDY

A Kenyan entrepreneur has cooked up a fuel-efficient stove and oven that uses less of a precious national resource: wood from trees.

Most African households using fuel-burning stoves either cannot afford clean-burning fuels like natural gas or electric stoves, or do not have access to them. They are stuck having to burn wood or other materials like animal dung – collectively called biomass – on open fires.

As well as using up wood and contributing to deforestation, there is another downside to these stoves. The use of polluting fuel-burning stoves by half the world’s population – including 80 percent of rural households – is a documented contributor to a host of health problems. Poor households not only have to contend with the ill health effects of dirty water and poor sanitation, the fumes from burning dung, wood, coal or crop leftovers lead to the global deaths of more than 1.6 million people a year from breathing toxic indoor air (WHO).

Two solutions in Kenya are helping people to cook more efficiently (meaning less time wasted on gathering material to burn, and less fuel used) and reducing cooking time by using heat more effectively.

Invented by Dr Maxwell Kinyanjui, the Kinyanjui Jiko is a fuel-efficient charcoal oven that comes in small, medium and large industrial sizes. Made entirely in Kenya, the ovens are custom designed for a variety of environments, from domestic household use and on-the-go safari models to high-capacity models for micro-enterprises and large institutions. Cooks can use the ovens to bake, toast, steam or boil. And they are 40 percent cheaper than cooking with electricity and between 15 and 20 percent cheaper than gas.

Kinyanjui’s Musaki Enterprises Ltd. (www.reskqu.blogspot.com/2009/01/arboretum-project.html) has developed a reputation for pioneering work in developing fuel-efficient stoves and ovens. Its most popular success to date has been the Kenya Ceramic Jiko (jiko is Swahili for cooker), or KCJ, a cheap, simple and effective stove. The company was set up in 1992, but has been involved in international aid-funded research and development efforts since the 1980s.

“My dad was on a very good team of highly motivated individuals in the early 80s who developed the stove through pragmatism, logic and good old-fashioned ingenuity,” said his son, Teddy Kinyanjui. “He then set up the independent Musaki Enterprises.”

The KCJ uses a ceramic liner placed inside a metal container. The metal is usually recycled, often taken from 55 gallon steel drums. The ceramic liner stops the heat energy from simply escaping into the environment and helps to focus the heat on cooking. Simply adding the ceramic liner reduces the stove’s fuel consumption by between 25 and 40 percent. The charcoal or wood sits in the ceramic basin and the burnt ash falls through holes in the bottom of the liner.

The stove design was a result of international and Kenyan cooperation, and has become popular in many African countries, including Uganda, Rwanda, Ethiopia, Malawi, Niger, Senegal and Sudan. It is used in 50 percent of urban homes in Kenya and 16 percent of rural homes.

Musaki Enterprises say the KCJ stoves on average save between 1 and 1.5 tons of CO2 per stove per year compared to other models. In supermarkets, the KCJs retail for around US $5 and the Kinyanjui Jiko ovens start at around US $100.

The deployment of the KCJ stoves has helped in slowing the deforestation of the country, but has not been able to bring it to a halt because of population growth and poor re-forestation efforts, says Teddy Kinyanjui.

“The lack of forward planning in tree planting is making firewood and charcoal harder and harder to obtain,” he said. “Fossil fuels are unavailable or unaffordable. Tree planting must begin now on a huge scale for people to continue cooking.”

Teddy won’t reveal how profitable the KCJ stoves have been, but says, “I wouldn’t have gone to school if they didn’t sell well.”

“Well, more and more people keep buying the damn things as fast as we can make them, so I think our customers like them,” he said. “They really all seem to like that the stoves cook really well for really cheap and are very high quality.”

Development Challenges, South-South Solutions was launched as an e-newsletter in 2006 by UNDP’s South-South Cooperation Unit (now the United Nations Office for South-South Cooperation) based in New York, USA. It led on profiling the rise of the global South as an economic powerhouse and was one of the first regular publications to champion the global South’s innovators, entrepreneurs, and pioneers. It tracked the key trends that are now so profoundly reshaping how development is seen and done. This includes the rapid take-up of mobile phones and information technology in the global South (as profiled in the first issue of magazine Southern Innovator), the move to becoming a majority urban world, a growing global innovator culture, and the plethora of solutions being developed in the global South to tackle its problems and improve living conditions and boost human development. The success of the e-newsletter led to the launch of the magazine Southern Innovator.

Health Care On The Cutting Block: Ministry Hopes For Efficiency With Search And Destroy Tactics

By David South

Today’s Seniors (Canada), August 1993

It’s search and destroy time at Ontario’s ministry of health: search out savings and destroy inefficiency and waste. But many remain apprehensive that not all the cuts are going to be logical and fear the province’s health and well-being will be affected. 

As part of the social contract deal, the Ontario Medical Association must find $20 million in cuts from the list of services covered by OHIP. The OMA and the provincial government are currently haggling over which procedures and examinations will be cut. 

“We look at services that aren’t medically necessary,” says health ministry spokesperson Layne Verbeek. “Because we were wealthier in the past, we were able to cover some services. We aren’t in that position now. But I don’t see how eliminating medically unnecessary treatments will affect the population.”

The fallout of the Rae government’s attempts to reign in costs and recover lost revenues may take years to unfold, but it is already apparent that Ontarians will be paying more. 

“Access to necessary treatment should not depend on a person’s ability to pay,” says health policy critic Carol Kushner. “What disturbs me about any delisting program is that virtually every medical service could be termed medially necessary. There are very few services that are an out-and-out waste of time.

“We often point to the fact that Ontario spends $200 million a year treating the common cold. Well, most of that is a waste of time. But delisting even that kind of service would be a detriment to the public’s health, because a small group of patients really do need to see a doctor when they have a cold.”

OMA spokesperson Jean Chow says it’s too early to pin down the exact cuts that will be made. “It’s a little premature to try and speculate what the final list will be.”

The newly-created Non-Tax Revenue Group is hard at work finding fees, fines and penalities the government can add or hike to boost revenue from this source from $5 billion to $10 billion a year. 

The spring budget saw the first hit, with the addition of $240 million in non-tax revenue. 

A radical reshaping of medicare is taking place. Private sector services – for which consumers pay directly or through insurance companies – now make up 34 per cent of Ontario’s health care funding, compared to 42 per cent in the United States, according to a recent study by the Canadian Medical Association. 

Health minister Ruth Grier has also floated the idea of widespread hospital closures. Both the Toronto and Windsor district health councils (DHCs) are carrying out feasibility studies on “reconfiguration.” The ministry is remaining tight-lipped about which hospitals will get the chop. 

“One suspects there’s room for efficiency – there are a lot of empty beds in a number of different places,” says ministry spokesperson Verbeek. 

“All hospitals are being reviewed, with a view to closing one or two hospitals,” says health planner Lisa Paolatto, who is working on a feasibility study on “reconfiguration” for the Essex County District Health Council, along with Toronto’s DHC. 

Closing hospitals could present a serious political hot potato for the government. In Britain, the Conservative government is still recovering from the bad feelings surrounding proposals to close world-renowned hospitals in the London area. The public feels great loyalty to local hospitals, a feeling that has been further fostered by hospital charities that raise millions a year from the communities’ good will. 

“This is going to open up new discussions of money between doctors and patients,” says Kushner. “Seniors are a unique group in Canada because they remember what it was like before medicare – what it was like not to be able to pay for the doctor, to forgo treatment that they thought was necessary. They understand the financial hardship that could occur if they were unlucky enough to have a family member who needs expensive medical treatment.”
